On this occasion we learn how to install COS on a 3 phase electrical panel. COS is an abbreviation for Change Over Switch, which functions as a power switching switch consisting of 2 inputs (incoming) and 1 output (outgoing). Input 1 comes from PLN electricity and input 2 comes from the stabilizer.
Hopefully this video is useful for friends who are studying 3 Phase Electrical Panels.
Electrical Panel Dimensions: 70 x 100 x 30 cm
